A job evaluation plan provides for five labor grades, of which grade 5 has the highest base rates and grade 1 the lowest. The linear plan involves a range of 50 to 250 points for skill, 15 to 75 points for effort, 20 to 100 points for responsibility, and 15 to 75 points for job conditions. Each of the four factors has five degrees. Each labor grade has three money rates: a ‘low,’ a ‘mean,’ and a ‘high’ rate.

a) If the high money rate of labor grade 1 is $8 per hour and the high money rate of labor grade 5 is $20 per hour, what would be the mean money rate of labor grade 3?

b) What degree of skill is required for a labor grade of 4 if second-degree effort, second-degree responsibility, and first-degree job conditions apply?

Question 1: In the casino game Roulette, a bet on “red” will win if the ball lands on one of the 18 red numbers of the 38 numbers on the wheel, with each number being equally likely. You want to run a simulation that will estimate the probability of a player winning both bets when betting on red twice. Which of the following would be an appropriate setup for the simulation:

I. Use a table of random digits to select one number from 01 to 38 and then a second number from 01 to 38. If the first number is between 01 and 18 and the second number is between 01 and 18, then the player has won both rounds.

II. Use a table of random digits to select two numbers 01-38, without repeats. If both numbers are between 01 and 18, then the player has won both rounds.

III. Use a table of random digits to select two numbers 01-19, allowing repeats. If both numbers are between 01 and 09, then the player has won both rounds.

A) I

B) II

C) III

D) I and II

E) I and III

In a survey, 100 adults in a certain country were asked how many hours they worked in the previous week. Based on the results, a 95% confidence interval for mean number of hours worked was lower bound: 30 hours and upper bound: 38 hours. Which of the following represents a reasonable interpretation of the result? For those that are not reasonable, explain the flaw. Interpretation #1: There is a 95% chance the mean number of hours worked by adults in this country in the previous week was between 30 hours and 38 hours. Flawed. This interpretation implies that the mean is only for last week. Flawed. This interpretation implies that the population mean varies rather than the interval. Flawed. This interpretation makes an implication about individuals rather than the mean. This is a reasonable interpretation Interpretation #2: We are 95% confident that the mean number of hours worked by adults in this country in the previous week was between 30 hours and 38 hours. Flawed. This interpretation implies that the population mean varies rather than the interval. Flawed. This interpretation makes an implication about individuals rather than the mean. Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. This is a reasonable interpretation Interpretation #3: We are 95% confident that the mean number of hours worked by adults in a particular area of this country in the previous week was between 30 hours and 38 hours. Flawed; the interpretation should be about the mean number of hours worked by adults in the whole country, not about adults in the particular area. Flawed. This interpretation implies that the population mean varies rather than the interval. Flawed. This interpretation makes an implication about individuals rather than the mean. This is a reasonable interpretation Interpretation #4: 95% of adults in this country worked between 30 hours and 38 hours last week. Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. Flawed. This interpretation makes an implication about individuals rather than the mean. Flawed. This interpretation implies that the mean is only for last week. This is a reasonable interpretation

Problem #5: Nine percent of men and 0.25% of women cannot distinguish between the colors red and green. This is the type of color blindness that causes problems with traffic signals. (a) If 9 men are randomly selected for a study of traffic signal perceptions, find the probability that between 2 and 4 inclusive of them have this type of color blindness. (b) In a group of 180 men, find the mean number that are color blind. (c) In a group of 180 men, find the standard deviation of the number that are color blind. (d) Suppose that a group of 180 men are randomly selected, and 27 of them are color blind. Is this a significantly high number that would perhaps suggest that the given percentage of men that are color blind (i.e., 9%) is not correct?

problem 6 :

Objective:

Write a program which simulates a hot potato game. In this version of a classic game, two or more players compete to see who can hold onto a potato the longest without getting caught. First the potato is assigned a random value greater than one second and less than three minutes both inclusive. This time is the total amount of time the potato may be held in each round. Next players are put into a circular list. Then each person gets possession of the potato in order. The player with the potato indicates how long they wish to hold on to it by entering a number from 1-10 seconds. If the player’s time is less than the remaining potato possession time then it moves on to the next player. However, if the time is larger, then the player is removed from the circular list and the potato’s time is reset. This is done until there is one player remaining.

Notes:

• The number of players has to be greater than 1 and specified by the user.
• Player’s then may enter their names.
• If a player picks a value outside of 1-10 then their pick is defaulted to 10.
• Once a game is over the user is prompted whether or not to play again.
• You must create your own circular linked list. This is very similar to the structure taught in class except the last element links to the first element.
• You may either choose to do a single or double linked list.
• Using multiple objects may make this the solution easier and extendable.

There is an insurance pool of 1000 people. All are covered via community rating. The distribution of expected health care costs per person is shown in the table below.

A. Year 1. Customers only buy insurance if their expected health care claims are higher than the premium. In the first year, 500 people purchase insurance. What is the highest premium the insurance company could charge to get 500 people to buy insurance? Explain.

B. Year 2. Expected health care claims are accurate. The insurer wants to cover costs, so they set their year 2 premium equal to the average claim for people who were covered in the prior year. What is the new premium? Explain.

A researcher wishes to examine the relationship between wage earned and educational level of workers. For a sample of 4000 workers she has data on hourly earnings (measured in Dollar), age of the worker (in years), worker’s gender, years of experience, number of years with the present employer, size of the firm in which the worker is employed, and highest educational qualification (with 4 classifications: no qualification, secondary school certificate, bachelor degree or PhD)

1. Explain how you would set up a model to address the researcher’s key interest.
2. Based on your model, how would you estimate the predicted impact on wages of holding a PhD compared to having a bachelor’s degree.
3. If the researcher uses ln(wage) as the dependent variable, how would the estimated coefficients be interpreted?
4. What general advice would you give the researcher in relation to her work – eg. what econometric issues should she be aware of in conducting this research and interpreting the results?
